The WB1JB335 is a low-consumption contactor coil from the TeSys range, wound for 220 V AC at 50 Hz control voltage. It is the replacement coil for CV1B and CV3B contactors — the exact part a line-down situation calls for when that contactor's coil fails and the machine builder's BOM lists this order code. At 68 °F (20 °C) the inrush power draw is 120...145 W (700...840 VA, power factor 0.17), dropping to a hold-in consumption of 28...45 W (80...110 VA, power factor 0.38). The closed-circuit inductance is 1.37 H, and average coil resistance measures 6.29 Ω. These numbers matter for sizing the control transformer and verifying the upstream fuse or breaker doesn't nuisance-trip on the inrush peak. The control voltage limits are 0.85...1.1 Uc at 50 Hz, up to 131 °F (55 °C) ambient — so the coil holds in reliably down to 187 V AC and picks up at the full 220 V nominal. If your panel runs hot or the line voltage sags, this gives the operating window.
